MATHIAS JENSEN, OF ASTORIA, OREGON, ASSIGNOR OF ONE-HALF TO THE JENSEN CAN FILLING MACHINE COMPANY.

SOLDERlNG-MACHlNE.

SPECIFICATION forming part of Letters Patent No. 551 ,122, dated December 10, 1895.

Application filed May 31, 1895. Serial No. 551,293. (No model.)

T0 at whom it may concern:

Be it known that I, MATHIAS JENSEN, a citizen of the United States, residing atAstoria, Olatsop county, State of Oregon, have invented an Improvement in Soldering-Machines; and I hereby declare the following to be a full, clear, and exact description of the same.

The object of this invention is to szwe solder and do neat work in soldering the end seams of round cans.

The machine is of that class where the cans are rolled forward by an endless chain while soldered, but instead of submerging the seam in molten solder, as usual, the solder is applied by a revolving roller submerged in the molten solder, the same as shown and described in my Patent No. 516, 308, dated March 13, 1894, and the surplus solder is removed by a revolving wiper of same construction as that shown in my Patent No. 442,484, dated December 9, 1890.

Referring to the accompanying drawings for a more complete explanation of my invention, Figure 1 is a side elevation of my machine. Fig. 2 is a plan view of the same.

Fig. 3 is a vertical section on line :20 a; of Fig.-

1. Fig. 4 is a similar section on line'g y of Fig. 1.

The frame A consists of three pairs of legs A, A and A and two rails A to which the legs are fastened. A trough B to contain the solder is secured on top of the legsAand A and a roller 0 is mounted in said trough with one end journaled in a box 0'' bolted to the trough, and the other end secured by a set-screw O in a socket 0 which latter has a turned stem extending through a hole in the end of the trough B, and the solder is prevented from leaking by asbestos packing O, which is held around said stem by a follower 0 as shown in Figs. 2 and 1. The revolving wiper D is secured on an axle D which is journaled in a yoke or arms D This yoke is mounted loosely on its bolt or pin D, the latter being supported from the legs A and A by boxes D The yoke rests on the end of a screw D, which is threaded through a bar D extending between the legs A and A and fastened to the same. The screw D facilitates the adjustment of the wiper to and from the cans. (See Fig. 4.)

The cans IV rest onthe roller 0 at one end and on the soldering-trough B at the other while passing over the solder, as shown in Fig. 3, and on the bar E while passing over the wiper, as shown in Fig. 4, said bar E being fastened to the leg A at one end and the trough B at the other, and the cans are guided over the roller 0 and wiper D by the rails E,

which are fastened to brackets E, that are bolted to the trough B, as seen in Fig. 3. The endless chain F for rolling the cans forward over said roller and wiper is carried on two pulleys G and G at opposite ends of the machine. The pulley G is keyed to an axle H, which is journaled in a long box H, and this box is held bya screw H in the standard H the latter being bolted to the trough B. (Shown in Figs. 1, 2, and 3.) The pulley G is loose 011 its pin or shaft G which is secured in a nut G and held by a screw H in the arm H The arm H is held by a screw H in the upright arm H", which arm extends upward from the legs A as shown in Figs. 2, 1, and 4.

The driving-pulley I and a smaller pulley I beside the chain-pulley G are keyed to the axle or shaft 11, and a long shaft J is journaled in two boxes secured to the lower part of the legs A and A This shaft J has a pulley J secured thereon, which is connected by a belt J to the small pulley 1. Upon one end of the shaft J is fastened a sprocket-Wheel K, which is connected by a sprocket-chain K to another sprocket-wheel K This sprocket-Wheel is secured to the stem of the socket C by which the roller 0 is revolved. (See Figs. 1 and 2.) On and near the opposite end of said long shaft J is secured a pulley L, which is connected by a belt L to a small pulley L This pulley is secured to the axle D to which the wiper is also secured. (See Figs. 2 and 1.) An arm M, weighted at one end and carrying a small 5 pulley ll at the other, is mounted loosely on the end of the shaft J. The weighted end holds the pulley M against the belt L and insures the required tension, while it permits the wiper to be adjusted to or from the cans. (See Figs. 2 and 4.)

An arm N is fastened to the upright arm of the legs A and extends over the wiper close above the lower line of the chain F to prevent IOO the wiper from throwing the cans out of place. (See Figs. 2, 1, and 4.)

The wiper should be made very flexible by light steel or rubber springs on the opposite side to its wiping-surface, and when made of ordinary cloth it should be kept damp either by a roller in water, as shown in my Patent No. 2,484, or by a light spray of steam and water. I prefer to make it with a series of leaves D secured in rows on its periphery, as seen in Figs. 1, 2, and 4c.

The solder may be heated by any of the usual modes for that purpose.

The operation will be as follows: lVhen the driving-pulley I is revolved in direction shown by the arrow, the chain F, the roller C, and the wiper D are all actuated by the connections previously described, and when the cans arrive at the entrance of this machine they are guided so as to enter properly between the roller (3 and chain F. Then the latter will engage the cans and roll them forward with their end seams in contact with the upper surface of the roller 0, which being submerged in molten solder and revolving will continually carry solder to the fiuxed seam, which will thus be made tight. As each can leaves the roller, it is immediately engaged by the wiper, which removes the surplus solder.

The machine, as shown in the drawings, is adapted to solder only one end seam at a time; but both ends may be soldered at the same time by carrying the cans on two rollers parallel with each other.

It will be seen that the solder is applied to a much less surface of the cans by using the roller than by submerging the scam in the molten solder; also the surplus of this smaller surface may be more perfectly removed by wiper, as stated.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, of a frame, a solder tank extending longitudinally along the same, a rotatable roller submerged in the molten solder, and supporting one end of the can whereby the solder is applied to the end seam of the can, said can having its opposite end supported by the tank, an endless chain whose lower fold travels in contact with the upper surface of the can and causes the can to be rolled forward in a direction at right angles with the direction of rotation of the roller and means for operating the chain.
